The Schneider Electric LV848752 is a MasterPact MTZ2 40 HA10 switch disconnector rated for 4000 A continuous at 1150 V AC, 50/60 Hz. It carries a 105 kA peak short-circuit making capacity (Icm) at that voltage, meaning it can close onto a fault without welding contacts — the rating that matters for upstream coordination in high-fault-current distribution boards. The drawout chassis mounting lets you rack the unit out for isolation without disturbing power wiring, which saves hours during switchgear maintenance or replacement.
Duty and isolation
Rated for AC-23A and AC-3 utilisation categories, this disconnector handles both motor switching (AC-3) and mixed resistive-inductive loads including occasional motor starting (AC-23A). The 50 kA short-time withstand (Icw) for 3 seconds gives selectivity headroom downstream — a fault clears without upstream tripping as long as the downstream breaker opens within that window.
